What do you have to do in this traffic situation?

Your answer is correct.

In this traffic situation, the stop sign requires you to stop completely at the designated stopping point, which is usually the line of sight where you have the best view of oncoming traffic. Even if there is no explicit stop line on the road, you must stop before entering the intersection to check for cross traffic. This is essential for safety and to avoid collisions.

The rule in German traffic law is clear: when you see a stop sign, you must stop, look carefully for other vehicles or pedestrians, and only proceed when the way is clear. Stopping is mandatory regardless of whether other traffic is immediately visible or not.

This ensures that you give right of way properly and helps prevent accidents at intersections. So, stopping at the line of sight and giving way as required is the correct approach.
